Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transceiver coils are used for multi-nucleus scanning, then the imaging capability for different nuclides is improved, but the difficulty of identifying and positioning multi-nucleus coils in hydrogen nucleus images increases
Solution Approach 1:
The patent introduces coil identification markers as intermediary elements that can be detected in hydrogen nucleus images. These markers serve as mediators between the multi-nucleus coil and the imaging system, enabling the coil to be visually identified and positioned without requiring complex detection algorithms or additional specialized imaging sequences.
2Measurement precision
If manual physical adjustment of object position is performed to ensure ROI is within imaging range, then the positioning accuracy is improved, but the scanning time and operational complexity increase
Solution Approach 1:
The patent performs preliminary identification of the multi-nucleus coil position and imaging range before the actual multi-nucleus scanning begins. By visualizing the coil and determining its imaging range in advance using hydrogen nucleus images with coil identification, the system prepares all necessary positioning information beforehand, eliminating the need for time-consuming manual adjustments during the scanning process.
Solution Approach 2:
The system provides visual feedback through hydrogen nucleus images displaying coil identification markers and determined imaging ranges. This feedback mechanism allows operators to immediately see the coil position and imaging range, enabling automatic adjustment of scanning parameters without repeated manual trials and adjustments.
3Ease of operation
If coil identification markers are added to multi-nucleus coils, then the ease of positioning is improved, but the device complexity increases
Solution Approach 1:
The patent employs coil identification markers that can be visualized through signal intensity changes or contrast differences in hydrogen nucleus images. These markers utilize signal characteristics (such as different relaxation times or signal intensities) rather than complex structural modifications, allowing easy differentiation of the coil from surrounding tissues without adding significant structural complexity.
